What metallurgy can tell us about India’s history?

Most nation histories are studied from the angle of politics and sometimes from economics as well. However, looking at shaping of history from a scientific lens is as exciting and could be more informative as well. Evolution of metals and science is critical to shaping any country/nation/state.

Anil Kumar Suri has a nice piece on looking at India’s history from a metallurgical angle. Metals are of high interest to this blog given their crucial role in coins and currency:

The history of metallurgy in India can tell us a lot about the history of India itself. Our scientific heritage has inexplicably always been given short shrift in our history textbooks, as pointed out here and here. It is, therefore, not very surprising that our historians don’t enter at all into this rather technical, if extremely fascinating, aspect of our history.

The use of metals marks major epochs in the history of any culture. The Bronze Age in India began around 3000 BCE in the Indus Valley region. The ancient cities of the Indus Valley Civilization (2600-1900 BCE) were part of India’s Bronze Age. The Indus Valley Civilization, also called the Mature Harappan phase, is merely the most well-known period of the Indus Valley Tradition (7500-300 BCE), which began with Neolithic (i.e., New Stone Age) settlements, such as in Birrana, Haryana (c. 7500 BCE) and Mehrgarh in Baluchistan, Pakistan (c. 6750 BCE). Another group of Bronze Age nomadic tribes, the Indo-Aryans, were believed to have entered the subcontinent in the second millennium BCE, contributing, in some versions, to the decline of these cities; the Indo-Aryans settled down in what is today Punjab and Haryana (where they composed the Ṛg Veda), slowly moving eastward and eventually founding their own cities on the Gangetic plains, in what is known as the Gangetic Tradition. These Indo-Aryans were also supposed to have begun India’s Iron Age around 1000 BCE.

Although archaeologists now overwhelmingly agree there is no evidence of such an invasion or migration, and inspite of it being based almost exclusively on unverified philological arguments, the supposed advent of Indo-Aryans continues to be the norm in academic discourse, is what is taught in textbooks, and guides prevailing constructs of ancient Indian history, such as a supposed culture shift that I had tried to examine earlier. Here, I try to look at India’s history from a more technological perspective. The picture that emerges shall not only leave us much better informed about India’s ancient history, but may undo our current simplistic notions of Stone, Bronze and Iron Ages.
